CVE-2024-6763 Overview
Eclipse Jetty is a lightweight, highly scalable, Java-based web server and Servlet engine. It includes a utility class, HttpURI, for URI/URL parsing. The HttpURI class does insufficient validation on the authority segment of a URI. This behavior differs from common browsers in handling URIs that would be considered invalid if fully validated against the RRC. Specifically, HttpURI and browsers may differ on the value of the host extracted from an invalid URI, potentially leading to open redirection or SSRF if the URI is used post-validation checks.
Critical Impact
The vulnerability can lead to open redirect and SSRF attacks, affecting data integrity.

Technical Details for CVE-2024-6763
Vulnerability Analysis
The vulnerability occurs due to improper validation in the HttpURI class, which can lead to discrepancies between HttpURI and browser-parsed URIs. This opens the potential for an attacker to exploit differences and redirect or read server-side resources inappropriately.
Root Cause
The root cause is inadequate parsing and validation of the authority segment in URIs by the HttpURI class of Eclipse Jetty.
Attack Vector
The attack vector is network-based, allowing remote attackers to exploit the URI parsing logic if the targeted application relies on HttpURI.
// Example code snippet that may be affected by the vulnerability
HttpURI uri = new HttpURI("http://example.com:80");
System.out.println(uri.getHost()); // May differ from browser interpretation
Detection Methods for CVE-2024-6763
Indicators of Compromise
- Unexpected redirects in network traffic
- Anomalies in server logs corresponding to user-requested URIs
Detection Strategies
Monitor network traffic for unusual redirect patterns and compare parsed URI components between server and client requests.
Monitoring Recommendations
Implement logging for HttpURI usage and analyze discrepancies in host parsing logs compared to standard browsers.
How to Mitigate CVE-2024-6763
Immediate Actions Required
- Update to the latest patched version of Eclipse Jetty
- Review and audit application code using HttpURI
Patch Information
Refer to the vendor advisory for patch details: Eclipse Jetty Security Advisory.
Workarounds
Implement strict URI parsing and validation before processing.
